No, I didn't start grad school (although I'm still thinking about it...). Instead, I started a Mandarin class. A few of us at work who travel to China wanted to be able to communicate at least a little while we're over there, so we signed up for a class from DeAnza College. It's five days a week for an hour during lunch, and it goes until mid-December.
Conclusion so far: I'm really bad at Chinese.
Other conclusion: college students are really young these days.
I studied Spanish for long enough that I'm reasonably fluent now, but it's really hard to start again at square one with a new language. Doubly hard when the language includes a bunch of sounds you've never made with your mouth before. Triply hard when its writing system is completely foreign to you.
Wish me luck.
